I’ve finished building the signal generator for the ham radio workbench. It still needs some work.

A curious line of thinking… What if Stonehenge wasn’t built to transmit anything at all? What if it was designed to remove noise?
In this video, we explore an unusual collaboration between Dr Arnold Schwarz (Technical Institute of Munich) and Professor Barker (OU Milton Keynes), and a series of experiments that led to some rather unexpected results.
Topics touched on include:
multi-channel correlation
atmospheric noise cancellation
low-noise receive systems
ground-referenced signal stability
If you’ve ever experimented with LoGs or other receive antennas, some of this may feel… oddly familiar.
That said… the discussion around noise, correlation, and receive antennas is very real. The “research”, professors, field work, and documents were created using AI tools and a slightly overactive imagination. Filmed and published on April 1st. If you made it this far without raising an eyebrow… well done.
And if you spotted the “anomaly”… even better.
PocLink’s new devices offer revolutionary communication. The Ultra works on any cellular network. The PocOne Pro connects via cellular OR Wi-Fi (like Starlink), even bridging devices across networks. #PocLink #OffGrid #Communication #Tech #Starlink
In this video, I take a closer look at one of the most common debates in ham radio:
👉 Do you actually need a hotspot for DMR?
There’s a persistent belief that DMR radios are “basically internet devices” and that hotspots are required. So I decided to test that idea and see if it’s possible to skip the hotspot entirely and still make contacts.
Using a Radioddity GD-168 (Anytone D168UV), I walk through a setup that connects directly to a network router and accesses DMR talkgroups without a traditional hotspot.
Along the way we’ll cover:
• What a DMR hotspot actually does
• How DMR radios connect to networks like BrandMeister
• Whether you can operate DMR without RF
• The role of internet vs RF in digital voice modes
• And why this topic causes so much debate in the ham radio community
If you’ve ever wondered:
• “Do I need a hotspot for DMR?”
• “Can a DMR radio connect directly to WiFi or Ethernet?”
• “Is DMR just internet?”
This video will definitely give you something to think about – like that it was published on April Fools Day.
@charlesneal4603 is wondering how much of the "effective" part of the antenna is included when wrapping wire around an insulator. Does the antenna end where the wire wraps back, or at the start of the insulator?

Scheduled power outages are increasing. Experts advise preparing with radios and batteries. Consider solar charging systems for reliable power during extended outages. This isn’t extreme; it’s becoming normal. #PowerOutage #PrepareNow #EmergencyPreparedness #GridReliability #UtilityAlerts
This video is a commentary and rebuttal to a video that I found that claims GMRS is better than Ham Radio for disaster preparedness and Emcomm (Emergency Communications)
I found a video from @RANTStrategies that claims GMRS is better than Ham Radio in Emcomm. Is it? He makes some good points, but is also wrong in some areas, so let’s break this down.
